Beit known that I, (.lnAnnns W. DMW., a

citizen of the UnitedStates, residing at thc cilyof lrandl Rapids, county of Kent, State 5 vol" lijlicliigan, have. invented certain new and useful Improvements in lllastic-l*`luid Generators, ol' which the f ,ollowingis a specification. '.lhis invention relatesto improvements in generators i vMy,improved generator is particularly designed hy me for converting a dense fluid into anwelastic fluid for the driving of engines, although it is desirable for use in various other relations, as for heating purposes.

lhe main objects of this invention are, first, to provid(` an improved generator of thc r=lassdes1,:|'il cd which is highly ellcicnt and economical in thc ['n'oduction of elastic iluid. Second, to irovidc an improved generator of the class rlcscribed which is compact and economical in structure and not likely to get out of repair in use.

Further objects, and objects relating to details of construct ion, will definitely appear from `the detailed description to follow.

' :l accomplish the objects of my invention by the devices and means described in the following slncilication.

'.lhe invention is clearly defined and pointcd-out inthc claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this speciication, in which, l

,Figure l is a central vertical section of a structure embodying the features of my invention; Fig. .2 is a horizontal section taken i .onf aline corresponding to the'broken line 40 S-S (rf-Fig. l, portions only of the coil being sectioned; Fig. 3 is a side elevation of the supcrlnvatin(r cone 2 3 and Fig. 4 is an inverted plan of tl ie cap 3, the cone 5 being shown intransvcrse section.

In the drawing, the sectional views are` taken looking in thc direction of the little CII arrows at the ends of the section lines, andsimilar numerals of reference refer to similar parts throughout the several views.

lteferrin`- to the drawin 1 is a casting from. whicll supported. This casting 1 is provi ed with ,a delivery chamber 22 for the elastic'iluid, and also with a delivery passage 24 for the 65 delivery chamber.' The casting 1 is also Specification o! Letters Patent. Applicationled April 10, 1907. Serial No. 367,463.

the parts of t e' gener tor are.

ELABTIC-FLUID GENERATOR.

Patented Sept.v 1, 1908.

preferably provided with a sup orting flange 25 by which it may be connected to an engine,

if desired. Below the casting 1 is an inverted conical superheating chamber 2l having an outwardly-projecting flan lre at its upper end adapted to rest on an annu ar flange rovided therefor in the casting l. The wa s of the su )crheating chamber 2 are preferably spirally-corrugated to form a spiral groove 2. l The superheating chamber is clamped by a threaded member 3, which has an opening 21 therein connecting the' superheating chamber to the delivery chamber 22. Within the superheating chamber is an inverted baffle cone 5 opening at its lower end and connected at 70, its u )per end to the clamping member 3. 'lhe delivery chamber is provided with a cap or cover 4.

About the cone I arrange the heating coils (i, which are connected at their delivery end 62 to the passage 18, which is in turn connected to the annular passage 19 formed in Ithe clamping member. This passage 19 is connected by a plurality of ports 20 to the super-heating cone, the ports 2() opening into 30. thc superhcating chamber outside of the baille cone 5, so that any fluid passing through these ports must pass down the walls of the superheating cone to the lower end thereof beforev entering the delivery chamber 22 through the bafiie cone. The iluid to be converted is conducted to tljle coils through the pipe 6.

Arranged below the superheating cham- -ber is a burner7 the burner illustrated being 9,0

designed for burning gasolene, alcohol, or the like. The fuel sup )ly pi )e 9 is coiled about thc burner above the fue cup 14 and about the upperend of the burner tube .'7, and connected to the inlet passage ,10 in the body 11 95 of the burner. The burner is provided with a needle valve 8', the stem 8 of whichprojects downwardly for convenience in manlpulat ion. A suitable packing gland, as 15, is 'provided for the valve stem. 10e

In starting the burner, the valve 8 -is l o cned, when the liquid' fuel will flow. down t rough the passages 37 into the generating cup 14 of thebm'ner.. The fuel is ignited in this cup and gas isgenerated in the supply 1 6 pipe, which is coiled above the burner cup,i

as stated, and in the base of the'burner. The burner is provided with a burner tube 7 having a plurality of air inlet openings 12.-4 /The :burner tubeffis arranged tliroughthe bottom 11o 2) of thc main casing with its air ports 12 below the bottom, the burner tube being preferably threadei'l through the bottom. rllic inlet ports 12 are provided with a suitable slceveelikc valve 13. lfn thc side of the casing 35 for the burner is an opening lo provided with a suitable door 17 through which the fuel in the burner cup' 14: may be ignited. The door 17 is preferably in the form of a slccvc surrounding the base of the casing, it being secured in position thereon by rivets 17 arranged through suitable Islots therein.

The generating coils and the burner are surrounded by a casing preferably double walled, consisting of an, outer casing 27 and an inner casing 28, between which is a suitable insulating material 32, suc'h as asbestos or mineral wool, for preventingr the cold air striking the generating coils and superheab ing chamber; and also for preventing radif ation of the heat. At`the top of thc casingf is a chimney or flue 33 for carrying off the products of combustion.

The chamber 22 is preferably provided with a safety valve 26 which delivers into the flue The safety valve 26 is prcferably a poppet valve, held in positiofr| l: .ya

suitable sp-ing, the same being seatediin thc outer end of the passage 23.

The upper part of the casing is preferably made detachable and is preferably arranged on the* lower part like a cover, so that it may be removed to afford ready access to the interior. The casing is provided with an opening 30, through which the burner may be ignited. This opening is provided with a suitable door 31.

In operation, the fuel, whichmay be gasolene, alcohol, or other inflammable material, is admitted to the burner through the valve 8. The fuel will run out into the burner tube and down'through the hole 37 into the generating cup 14. The valve is then closed and the fuel in the cu ignited. This heats the sup ly tube 9, which is coiled above the cup, and) the base of the burner, as\described converting the liquid fuel therein into a gas. The needle valve is then opened and tliegas flows up througn thcbu rncr tube 7, drawing in suflicicnt air to make a-proper burning mixture through the o )enings or' air ports 12. rlhc llame from tliic burneris'urrouI-ids -.the generating chamber 2, heating it to a very high temperature. The coils 6 also become very hot. W'hen the whole is suflciently hot, the denser Iluid, such as Water, is forced up through the coils 6 to the super-4 heating chamber. The fluid is at this time converted or almostlconvertcd into an elastic iluiil. The generating cone, being ver-y hot, the fluid', by passing downwardly over this to the lower end of thebaflle cone, is converted into a su perhealcd elastic fluid, in which condition it passes up through the baille cone into the delivery chamber 22 and thence is delivered to the engine, or. for any other dosii'ablc purpose,

".l`hc supcrhcating conc is, as before described,l )rovidcd with spiral grooves, so that, should tlic denser [luid not be coi'ivertr-d into an elastic fluid before entering the superhcating chamber, it will run down the spiral groove and in so doing be converted.

My improved generator is very iili-icnt and economical to operato. lt is illsosimplo und economical in structure, being very compact, and the parts boing readily assembled.

ly have. illustrated and described m` inin'ovcd generator in detail in thc form prelerred by me on account of its structural simplicity and economy und the convenience in use. l am aware, however, tl, it it is capable o f very great variation in details of construc- "tion without departing from my invention,
